Hebrews 4:5-8

And again, as stated before, They will not enter into my rest. Those who first heard the good news of deliverance failed to enter into that realm of faith’s rest because of their unbelieving hearts. Yet the fact remains that we still have the opportunity to enter into the faith-rest life and experience the fulfillment of the promise! For God still has ordained a day for us to enter into called “Today.” For it was long afterwards that God repeated it in David’s words, “If only today you would listen to his voice and do not harden your hearts!” Now if this promise of “rest” was fulfilled when Joshua brought the people into the land, God wouldn’t have spoken later of another “rest” yet to come.
